The result is a huge improvement in yield per watt and in bud density, trichome density, colors in your flowers and terpene profiles. You can expect yields of up to 2.25 pounds per harvest which is an incredible 2.25 grams per watt.

Both the COBs and the 3 watt diodes have the power to penetrate deep below the canopy. 120 degree secondary lenses focus the light even further to magnify PAR and increase the canopy penetration by up to 200%.

The PPFD at 18 inches is 658.92. The following table shows the PAR footprint over a 4x4 area at 18 inches.

The PPFD at 24 inches is 600.59. The following table shows the PAR footprint at 24 inches.

The recommended hanging height during flowering is 18 to 24 inches for a 4 x 4 foot coverage.

Hanging the light at 24 to 30 inches gives a coverage are of 4.5 x 4.5 feet.

For vegging, hang the light at 30 inches, using the COBs only. It covers a 5 x 5 area while vegging.

Perfect Full Spectrum Light

The COBs deliver a 3500K full-spectrum white light that is great for all stages of growth. The supplemental 3 watt LEDs add red, blue, white, UV and IR light to give plants even more of the wavelengths they need the most.

Light Controls On The Optic 4 XL

The Optic 4 XL features separate switches for the COBs and the 3 watt bloom enhancers. It also has separate dimming knobs for each.

The COB dimmer allows you to set the 4 COB LEDs between 10 and 100% power. The bloom enhancer does the same for the supplemental diodes (10-100% power).

The switches allow you to run only the COBs or only the supplemental diodes if you don't need full power. The following charts show the spectrum with COBs only and with all lights on.
